LEOPOLD WESTON AND JOHN REID J OF NORTHCQTE, AUCKLA1\TD, NEW ZEALAND.

BILGE-PUMP.

To all whom it may concern Be it known that we, LnoPoLn WESTON and JOHN REID JONES, 'bothcitizens of the Dominion of New Zealand, and residing at Rodney Road, Northcote, Auckland, 1n the Provincial District of Auckland, 1n the D0- minion ofv New Zealand, have invented certain' new and useful Improvements 1n Improved Bilge-Pumps, of which the following is aspecification.

This invention relates to pumps for pumping bilge water, more especially vtothat type disclosed in our copending appllcation bearing Serial No. 274,479, which pumps are operated by a pendulum when the vessel rolls in which the same are installed.

The present invention provides a pumpwith means for priming the same, for locking the pendulum when it is desiredto prevent the pump from operating, and for regulating the throw of thepump. Also means are provided for absorbing the momentum of the pendulum when the vessel oscillates excessively.

The drawing herewith illustrates the invention:

Figure 1, is a partsectional elevation of a vessel showing the pump in position,

Fig. 2, a side elevation of the pump on a larger scale,

Fig. 3, is a plan of a locking device,

Fig. 4, is a part front elevation of the pump,

Fig. 5, is a sectional elevation on line 5-5 Fig. 4,

Fig. 6, is a part plan of a race.

The means for priming the pump operates automatically with the rolling of the vessel, and comprises an upwardly sloping priming pipe 1 connected at one end to an upwardly sloping delivery pipe 2 and near the delivery valve 3 of the pump. The other end of the pipe 1 passes through the side 4 of the vessel immediately above the outer end of the delivery pipe 2. The end of the priming pipe 1 is fitted outside the vessel with an upturned scoop or flared mouth 5.

WVhen a wave covers the scoop or flared mouth 5 a quantity of water enters and runs down the pipe 1 to the delivery valve and displaces the air therein, the said air passing out of the pipe 2 at the side of the ship. The pump 6 is thus kept constantly primed and the starting of the same is insured at any time when it has failed to draw up the bilge water.

Specification of Letters Patent.

Patented June 3, 1919.

. Application filed April 4, 1919. Serial No. 287,595.

The device for locking the pendulum 7 comprises a plate 8 slidable on the base of the pump and adapted to be secured by studs or bolts 9 fixed 'to the said base and passing through slot 10 in the plate 8 and by nuts 11 on the bolts. One'encl of the plate has a raised jaw 12 adapted to pass over a race 13 in whichthe end of the pendulum rod 14 swings, and to engage the pendulum rod and secure the same. from oscillating.

The means for absorbing the momentum of the pendulum 7 when the vessel rolls excessively, comprise buflers 15 having stems 16 slida'ble in holes made in the ends 17 of the race 13, springs 18 being provided on the said stems between the heads of the buffers andthe ends 17. WVhen the vessel rolls excessively the end of the pendulum rod :14 strikes one or other of the buifers and its momentum is thereby absorbed.

. The-means for regulating the throw of the pump comprise disks 18 and 19 fitting upon a sided portion 20 of a spindle 21,-to

which the pendulum rod 14 is fixed, the said spindle being mounted in the standard 22 of the pump. The innermost disk 18 fits against a shoulder 23 formed on the spindle 21, and the disk 19 is slidable on the spindle.

The above disks may be made to turn with the spindle by means of a feather in a well known manner and not illustrated in the drawing, instead of making the spindle sided.

Between the disks 18 and 19 are provided dlsks 24 and 25 made of fiber and mounted upon a bush or socket 26 integral with the disk 18. Between the disks 24 and 25 is a central metal disk 27 having an arm 28 to which the connecting rod 29 of the pump is connected. Another arm 30 integral with the disk 27 is adapted to oscillate between stops 31 mounted on the standard 22 and adjustable laterally by means of bolts 32 passing through slots 33 made in the said, stops. A spring 34 on the spindle 21 is adapted to be compressed between the disk 19 and a washer 35 by means of a nut 36 screwed upon the spindle.

The friction set up between the disks 18, 19, 24 and 25 by means of the pressure of the spring 34 grips the central disk 27 sufliciently to operate the pump 6, but when the roll of the vessel is excessive the arm 30 strikes one or other of the stops 31 and ar rests the action of the pump at the predetermined limit of the throw of its plunger.

The throw of the pump is regulated by adjusting the stops 31 laterally as required.

This arrangement of disks also allows the pendulum to find its center of gravity and operate the pump when the vessel is sailing with a list either'to port or starboard.

The pump is made double acting by providing a second arm similar to arm 28 and a second pump similar to the pump 6, as shown by dotted lines in Fig. l.

lVhat we do claim and desire to secure by Letters Patent of the United States is 1. In a bilge pump, priming means comprising an upwardly sloping pipe having a flared mouth outside the vessel and connected to the delivery pipe of the pump near the delivery valve thereof, substantially as set forth.

2. In a bilge pump, the combination with a pendulum of an adjustable plate having a j aw to engage the end of the pendulum rod, substantially as set forth.

3. In a bilge pump, the combination with a pendulum and a race wherein the end "of the pendulum rod oscillates, of buffers at the ends of the race, substantially as set forth.

4. In a bilge pump, the combination with a pendulum and a race wherein the end of the pendulum rod oscillates, of buffers hav- Copies of this patent may be obtained for five cents each, by addressing the ing stems slidable in the ends of the race and springs between the ends of the race and the heads of the buffers, substantially as set forth. l

5. In a bilge pump, the combination with a pendulum and a spindle having a shoulder and to which the pendulum rod is fixed and having a sided portion of metal disks mounted on the said sided portion, a socket integral with the innermost disk which fits against the said shoulder, disks made of fiber mounted on the socket, a central disk mounted on the spindle between the fiber disks, an arm integral with the central disk, and to which the connecting rod of the pump is attached, another arm integral with central disk, laterally adjustable stops between which the said other arm oscillates, a spring mounted on the spindle, and a nut on the spindle for pressing the spring against the disks, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two witnesses.
